Are you always this rude to people on public mailing lists?

You want polite answers? Then pay me $150/hr and I'll give you polite
answers.

Seems to me that Patrick's answer contained less useful information than
mine which you carefully snipped off your reply. Here it is again:

   P.S. You might want to refer to some RFCs as well
   http://www.faqs.org/rfcs/rfc2072.html
   http://www.faqs.org/rfcs/rfc1812.html

Note that I didn't just refer to "some RFC" or "RFC 1812 and 2072" but I
actually took the time to dig up working URLs to the two RFCs. They talk
about CIDR and state quite definitively that all-ones and all-zeroes
subnets are allowed. 

   P.P.S. You're probably right but if you can't make the customer's
   equipment work and you can't back up your claims with reference to a
   higher authority, then you gotta be crazy.

Of course, what is allowed and what works are two different things.
And if the customer's router will not work as defined in RFC1812 then it
will help the guy immensely if he can point to the higher authority of the
RFC so that the customer realizes quite definitively that it is the
customer's equipment that is broke, not the ISP that is broke. At this
point if our ISP is smart he will work around the problem maybe by giving
the customer a couple of /26's or selling them a better router or...

You better get used to jerks on mailing lists because there are *LOTS* of
us out there, often providing useful technical info along with our rude
comments. Maybe your worst nightmare is the class clown who grew up to be
a geek but some people just snicker at our antics and go on to the next
message. And that's the way life oughta be.
